The general area around the Eugene Airport is good for wintering raptors and waterfowl, including Tundra Swan. Check hedgerows for sparrows and Northern Shrike. Other birds that favor open country can sometimes be found in winter, including Prairie Falcon, Horned Lark, Burrowing Owl, and (rarely) Snowy Owl.
From Site F10 continue W 5 mi on Clear Lake Rd. From Eugene go W on Hwy 126 to Greenhill Rd, then go N 2.4 mi to Clear Lake Rd. Best birding in this area is on side roads off of Clear Lake Rd and Greenhill Rd to N. Use caution and stop and park safely while viewing birds, as traffic moves fast on some of these roads.
